I've written about the link between insomnia and body weight a few times. Now a study has found that the higher your body mass index (BMI), the less sleep you're likely to get.
The study looked at 6,344 men and women aged between 20-60 years of age with a BMI range of 18-40 (this range covers the classifications of underweight, healthy weight, overweight and obese).
First of all, researchers once again found that women sleep more than men (regardless of BMI). Whilst the average man managed to get 6.6 hours, the average woman got 6.9 hours. This equates to women getting an additional 20 minutes of sleep each night.
Now to the nitty-gritty of the study. Researchers found that for both men and women, as BMI increases, sleep duration decreases. That being said, researchers found that sleep deprivation was more closely linked to higher BMI numbers in women, compared to men.
You may think that weight affecting sleep is obvious - however, only 46% of Americans are aware of the link between body weight and sleep, and only 26% consider sleep a factor when it comes to losing weight.
